I have a Europa Plus tester with firmware 0.28n. Is the Europa firmware update on the website (28t) suitable for this machine?

Secondly, another enhancement request (if not already in the newest firmware) - can "Limit Calc" for earth tests of extension leads be updated to allow 30m of 1.5mm2 and 50m of 2.5mm2 cable? I know you can manually enter a limit in ohms, but this would be more convenient.

I'm thinking specifically of 30m JoJo reels and the like, but also 15A/16A stage lighting extensions where 30+m lengths are common.
